Generally, a download manager enables downloading of large files or multiples files in one session.Many web browsers, such as Internet Explorer 9, include a download manager.Stand-alone download managers also are available, including the Microsoft Download Manager.

if you do not have a download manager installed, and still want to download the file(s) you've chosen, please note:

You may not be able to download multiple files at the same time.In this case, you will have to download the files individually.(You would have the opportunity to download individual files on the "Thank you for downloading" page after completing your download.)

Files larger than 1 GB may take much longer to download and might not download correctly.

You might not be able to pause the active downloads or resume downloads that have failed.

The Microsoft Download Manager solves these potential problems.It gives you the ability to download multiple files at one time and download large files quickly and reliably.It also allows you to suspend active downloads and resume downloads that have failed.

After you install the Reporting Services Add-in and configure your servers for integration, you can publish Reporting Services content to a SharePoint library and then view and manage those documents directly from a SharePoint site. The Reporting Services Add-in provides the following functionality:

Power View, a feature of Microsoft SQL Server 2012 SP1 Reporting Services Add-in for Microsoft SharePoint Server 2010 Enterprise Edition, is an interactive data exploration, visualization, and presentation experience. It provides drag-and-drop ad hoc reporting for business users such as data analysts, business decision makers, and information workers. Power View reports are in a new file format, RDLX.

Open reports in Report Builder from a SharePoint library, and save reports to SharePoint libraries.

SharePoint web pages so that you can create subscriptions and schedules, and manage reports and data sources.

Support for standard SharePoint Foundation 2010 and SharePoint Server 2010 features including document management, collaboration, security, and deployment with report server content types.

The ability to add the Reporting Services Report Viewer Web Part to any page or dashboard on a SharePoint site and customize its appearance.

The ability to use SharePoint permission levels and roles to control access to report server content. You can also use SharePoint forms authentication to support access over Internet connections.

Reporting Services data alerts, a data-driven alerting solution for SharePoint Server 2010 Enterprise Edition that informs you about changes in report data that are of interest to you, and at a relevant time.

You can install and configure the servers in any order, but integrated operations will not be available until the configuration steps are complete for both servers. For detailed information on the installation steps, see the Readme for the existing Reporting Services Add-in.

Step 5:Configure the Reporting Services SharePoint service and create at least one Reporting Services service application.

Step 6: Set permissions and add Reporting Services content types.

Step 7: Verify the installation.

The Reporting Services add-in should be installed on each SharePoint web server that you want to use for accessing the Reporting Services Local mode features or the connected SharePoint mode features such as Power View and data alerts.

Application pages that you use on a SharePoint site to view and manage report server items, and errors and warnings that appear on those pages, are available in the supported languages.
Messages that originate from the report server and reports that you design in Report Designer are available only in the languages supported by SQL Server 2012.
Report Builder for SQL Server 2012 supports the same languages as the Reporting Services Add-in. If you want to create a report that contains titles and labels in a language that is not supported by SQL Server 2012 and Report Designer, you can use Report Builder instead. For example, if you are using the Czech language version of a SharePoint product or technology and you want to create a report that uses Czech titles and labels, start Report Builder from a SharePoint site and create your report.
When you download the Reporting Services Add-in, you must choose a language. The Report Viewer Web Part (ReportViewer.dwp) will be available only in the language that you choose. The application pages and messages will be available in all supported languages, regardless of the language you select on the Download page.
